Wifi USB Adapter stops working intermittently

Pull out the doggle and post the same "iwconfig" output.
What happened to the "rfkill list" comand output? This will show if your wireless pci card is being blocked. If it shows an output then there is a button or key, or setting in the bios, that will turn it on. Seeings how it's a Samsung this is highly probable.

Edit: Press the FN + F9 keys to turn on wireless.
